Eddie Redmayne 'grilled' JK Rowling on Fantastic role

'Fantastic Beasts and Where To Find Them' star Eddie Redmayne got to meet author J.K. Rowling - who wrote the book and created the world of 'Harry Potter' - and quizzed her about his character Newt Scamander

Eddie Redmayne "grilled" J.K. Rowling about his character in 'Fantastic Beasts and Where To Find Them' when he got to meet the author.

The 34-year-old actor plays Newt Scamander in the upcoming 'Harry Potter' spin-off movie and one day director David Yates brought the creator of the wizarding world on set to meet the cast.

Redmayne was told that Rowling would only be around for an hour so he took the opportunity to ask her as many questions about his alter ego as he could.

In an interview with Collider.com, he revealed: "I got to meet J.K. Rowling. I had about three or four months prepping the film, and just about a month I think before we started filming, I was here in Leavesden and J.K. Rowling came and it was this sort of brilliant or slightly odd moment in which David Yates sort of introduced her and I knew that she was only gonna be here for an hour and I think I was sort of like, 'Hello, nice to meet you!' And just basically grilled her for an hour she came to set the other day and I was like, 'I am so sorry.' But it was so phenomenal."

Redmayne insists Rowling, 51, was able to answer his queries and has a complete view of what her characters are like and the world which they inhabit.

He explained: "She's so passionate about her characters and she has such a sense of their whole three-dimensional world and their history. I don't know whether it's just a paranoia from recently having played people that lived or living and sort of having all this world of research that you can go and do. But what's great about Newt is you can just go to J.K. Rowling and she gives it all."

In the film, magizoologist Newt is on a mission to capture various magical creatures and Redmayne enjoyed finding out from Rowling what the character's history is and what gave her the inspiration to create him.

He said: "I was surprised by his background and where the thoughts for the character had come from. They're all quite personal to her and that was sort of lovely ... What's wonderful about J.K. Rowling and David is that they also really enjoy collaboration, like you can come with ideas and throw stuff in."

Redmayne stars in 'Fantastic Beasts and Where To Find Them' with Ezra Miller, Colin Farrell, Ron Perlman and Katherine Waterston among others.

Newt Scamander (Redmayne), a socially-challenged animal whisperer of sorts, has to gather up the fantastic beasts which have escaped from his briefcase and are roaming 1920s New York. A suitably magical spin-off, with Rowling's screenplay skilfully balancing dark and light, and director Yates maintaining a thrilling pace…
